iOS (Jailbroken): One of the big complaints about running a third party browser like Chrome on the iPhone is that it's always a little slower because Apple blocks third party apps from using its Nitro Javascript Engine. Nitrous is a new jailbreak tweak that adds that functionality into any app you want.

With Nitrous installed, any app that accesses the internet can get access to the Nitro Javascript Engine through the Settings page. This includes all your browsers, like Chrome, but also any other app that uses a webkit browser, like Facebook or Twitter. We ran a few tests with V8 Benchmark Suite, and Nitrous does indeed give Chrome a hefty speed boost:

Chrome without Nitrous Score: 96

Chrome with Nitrous Score: 347

Safari Score: 360

Chrome isn't quite as fast as Safari still, but it's close enough. If you want a more comprehensive speed breakdown, head over to iDownloadBlog. Nitrous is a 99¢ downloads in the Big Boss Repository.
